Each of the spring fingers 341 carries a curved portion 342 at its upper end normally bearing against the upper walls of the guides 338 and 339. 343 indicates a spring finger also secured to the shank of the carrier The spring finger 343 extends upwardly be- The base of the guide 337 is out neath the spring fingers 341 and past the end thereof and is provided with a cross bar 342 provided with open eyes 343 and 344 through which the ends of the cord portions are drawn as hereinafter described. 343 indicates a pinion mounted upon one end of the arbor 336. 345 indicates a vertical guideway carried by the plate 303. 346 indicates a rack bar slidably held in the guieeway and in engagement with the pinion 347 indicates a bell crank lever mounted upon a standard 348 carried by the base 1. 349 indicates an arm provided with an annular upper end 350 swung upon the shaft 6. 351 indicates a link connecting thedepending end oi" the arm 34$) to the lower end of the depending portion of the bell crank 34?. 352 indicates a link pivotally connected at its lower end to the horizontal end of the hell crank 347 and provided at its upper end with a curved portion pivotally connected at its e):- trenie end lower end the rack bar 346. 354 indicates a cam secured to the shaft 6 from the inner face of which extend pins 355 and i It will thus be seen that when the operating lever 7 is swung in the direction of arrow that the pin 355 is carried into on gagenient with the arm 349 thereby drawing the arm in the direction of arrow and tilting the hell cranlr 34? on its pivot and raising the linlr 352 and rack 346 in mesh with the pinion 343 thereby swinging the carrier in the direction of arrow (see Fig. 2). When the lever 7 is swung in the opposite direction, of course, the pin 353 engages the arm 349 to perform the reverse operation, that is to say, swing the carrier in theopposite direction of arrow back to its normal position.

I will now describe the mechanism by which the guide piece 305 is raised and lowered in the guide way. The guide piece of the spring finger is provided with a lug extension 305*. indicates a l1nk pivotally connected at one end to the lug extension 305*. 358 lndicates an arbor journaled in a lug extension 359 of the plate 5. To one end of the arbor is secured an arm 360, to the inner end of which is pivotally connected the lower end of the link 35'? above desc ibed. 361 indicates an arm secured to the opposite end of the arbor 358. 362 indicates a cam way formed in the cam 354 363 indicates a link pivotally connected at one end to the arm 361 and atthe opposite end to a link 364, which is pivotally connected at 365 to the base 1 of the machine. The pivot pin connecting the links 363 and 36 1 together carries a roller 366, which co-acts with cam groove 362. It will thus be seen that when the cam 35% is turned in the direction of arrow (see F 3) that the cam roller 366 is carried outwardly toward the periphery of the cam and that, therefore, the arm 361. is carried in the direction of arrow carrying the arm 360 downward and thereby drawing the guide piece connected to the arm by the link 357 downward. 36? indicates a pin carried. by the guide piece 305. 368 indicates an arm swung upon pin 369 carried by the casing 301. 370 indicates a slot formed on the wall intervening between the caslng and guide 299. 371 indicates a horizontal extension to the arm 368.

indicates a tension spring connecting the arm 368 to the opposite wall of the cas 307.. It will thus be seen that when the sli piece 305 is carried vertically downward that the pin passes clear of the arm allowing the arm to be swung on the pin 369 to carry the lateralextension 373. thereof throughthe slot 3'70 and thereby tree he carrier to swing in the direction of arrow a. above described. 373 and indicate slots formed in the plate 5 in pro'xint ity to the outer or go thereof. and 376 indicate brackets secured to the sides ot the plate by set screws extending through the slots 373 and 3%. 378 indicates a spring finger secured to the bracket 375. 378" indicates a spring finger secured to the l;- ":icket 3'76 by a rivet 377 379 indicatcs a set screw extending through the bracket and bearing against the outer face 7 so as to adjust the tension of the finger upon the cord. The lingers 31 8 and 378 may be provided wi h outturned lip extens ons 380 so as to allow the ready entrance oi the cord therebetween.

The above structures serve to guide the cord into the groove in the edge Gftllfi plate 5 as each length is drawn off the stock.

Having descrioed the principal parts involvcd in. my invention I will briefly describe the operation of the same.

When the lever 7 i is thrown in the direc" tion of arrow the shaft 6 and cam sleeve before it enters the spiral portion. During spreading them apart and drawing the jaw 9 8 carried thereby are rotated in a similar" direction. During the initial movement of the cam sleeve 8 the roller 35 travels through he concentric portion of the cam groove this movement of the roller the needles 21 and 22 are held stationary. By the above operation the cam way 225 (see 3) is carried in the direction of arrow thereby carrying the roller 232 into the concentric portion or" the cam way and thereby raising the knife 210 into position ready for cutting. During this operation the stud 249 engages the arm 2&3 swinging it upward ant past a vertical position until brought into engagement with the rolier 2-l0 thereby depressing the corresponding end of the arm 238 against the pressure of the spring 241 thereby carrying the oppositely extending arm 239 in an upward direction to carry the slide piece 215 circumterent'ally of the plate and thereby feeding the cord 208 which is gripped by the spring ratchet finger 221 through the perforation 206 into position to be gripped between the jaws 265 and 266.

has been before described when the arm2 l3 approaches this position the head. 295 enters between the pins 289 and 265 from the jaw 266 thereby allow ing the fed end of the cord protruding through thehead 203 beneath the knife 21 to pass between the jaws 265 and 266. the pin 289 passes the base of the head i j 2.) such pin is released and the jaw inen'iber 26: is forced by the sp ing 290 againstthe jaw member 266 to the cord therebetween By the upward movement of the lever in the direction of arrow the cam 354iis rotated carrying the rolle" 366 outwardly in the cam groove 362 toward the periphery oi thecam thereby forcing the li ik lore":- tudinally outward and swinging the r 361 in the direction ot'arrow. The outw swing of the arm 361 which is oy the arbor 358, serves to carry the arm 364; also carried by the arbor 358 downward drawing upon the link 35? and c yir. gu de piece downward.

It will. of course be undo for initial downward movement in? an piece 305 is an idle movement as the has not been fed to the machine into on Inent therewith. By the same movoi. als the pin 355 is carried into engage'm with the arm 349 swinging the arr the direction of arrow and drawi the link 351 tilting the bell crank 3e: pivot raising the link and k :1 engagement with the pinion swinging the carrier 335 in the direction 0 arrow in an idle movement.

As soon as the roller 35 enters the spi portion of the cam groove 9 of the cam carrying the gravity sleeve 8 the lever 10 i the needles 21 and grooves 187 and 188 so ings of the eyes are in in g the arm 173 upward such movement being assisted the tension spr'i 179. means of he f 193* connectec the arm 178 the blocs r82 is carried upward carrying the ribbon fingers 195 and through the eyes of the needles the extreme ends of such spreading outwardly after their passage hrough the eyes into the form shown in 9. 11s the arm 2&3 is swung 111 the direction or arrow (see 1* the gravity dog 2 9 passes off the periphery of the cam piece 25'? and engagcs the then notch 246. The operat ng lever is swung in the opposite l. By this movement the disk in the opposite direction the notch 2&6 engages the p L r the arm 2&3 in the opposite direction As has been before stated the co arrow. A l 208 has been gripped between the jaws and 266 and therefore as the arm swings in the reverse direction the cord is crawn through t c p 2 =3 arouncthe peripheral edge of the late 5 toward the opposite side of the plate, is the over 7 assumes its final position and the arm 243 has reached the position shown in Figs. and 5 the roller 232 again engages the occentric portion 227 of the cam way 225 merohy drawing the nitm downward and dowi swinging the knife 2- i ord irom the steer;

the fed portion of c the arm 2 13 finally carrying the severed portion of the cord into the position shown Fig. 1. As the arm 2 13 reaches this position the jaw member 266 is means or the finger 272 en. clined portion or" the cam p in hereinbetore been described thereb releasing the cord. Also by the reverse men-,1 of the lever 7 the carrier 335 is swung back to its normal position or the position shown in the drawing and the guide piece 305 raised. in order that the inwardly projecting portion 31 1- should pass the cord carr cd hi the upper edge o the plate 5 as the guide piece 305 assumes its uppermost position the inc ined portion 325 of tongue 3A: engages the horizontal of the bell crank 327 thereby torcin the member outwardly on its pivot the pro sure of the sp 329 th reby allowing the inwardly projec ing end 314: to pass the cord. It will, of course, be understood that the cord bridges the open upper end of the open the tongue 32% passes above the horizontal arm 327 the inwardprojection 314: passes over the cord. 7

S niuitaneously with the upward movement of the slide piece 305 the pin 367 carried thereby engages with the arm 36S forcing it into the vertical position shown in the drawing against the tension of the spring 372,'the horizontal portion 371 passing over the body of the car ier and beneath the spring fingers 241 thereby holding the carrier accurately in position to receive the cord. As the lever 7 is again swung in the direction of arrow the slide piece 305 is carried downward by means of the cam way 362, co-acting roller 366, link 363 and swingable arms 361 and 360 connected by the link 357 to the slide piece. As the slide piece passes downward the tongue 32% en ages the such tongue to pass downward without at footing the position of the extension 31-h Simultaneously the projection 317 is carried out of engagement with the projection 330 enabling the tension spring 318 to draw the member 315 vertically and carry the inward extension 321 upward to grip the center of the cord against the extension 314. It will thus be seen that as the slide piece 305 passes downward that the center portion of the cord is drawn downward into the guideways 338 and 339 of the carrier 335.

It carried into the position shown in the drawthe cross bar 34-2 and curved portion bear against the vertical edge of the lateral extension 321 As the cord is drawn into the guide-ways 338 and 339 it is also drawn into tie oycs 3413 and 3 1 1 being drawn longitudinally therethrough until the slide piece assumes its lower or dotted po sition shown in Fig. 5 drawing the cord into looped form.

lVhen the lever 7 is swung in the direcion of arrow the pin 355 engages the arm 19 pulling on the link 351 raising the horiand rack 3 16 so as to rotate the pinion 3 13 and swing the carrier 335 in the direction of arrow. The cord ends projecting from the eyes 3 13 and 34 i pass between the spread apart ends of the ribbon fingers 195 and 196. The iingers'195 and 196 are then draw-n down by means of the pawl 176 may be stated that as the carrier is .ontal arm of the bell crank 3417, link 352 passing out of the recess 158 carrying the cord through the eyes of the needles.
